SPECIFICATION forming part of Letters Patent No. 319,673, dated June 9,1885.' Application filed May 4, 1885. (No mear-1.)

.To all whom t may concern..-

Be it known that we, WILLIAM P. GALLA- HAN and THoMAs DE ARMoN, citizensof the United States, residing at Dayton, in the county of Montgomeryand State of Ohio, have invented certain new and useful Improvements inBoxes for Oil-Presses, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification.

Our invention relates toy improvements in boxes for oil-presses, and hasfor its object the production of boxes better adapted to bear thenecessary strain and pressure incidental to this class of presses, andit relates more particularly to that class of boxes known as telescopicboxes.77

Hitherto these boxes have been made of cast metal, and great difficultyhas been encountered in their use by the frequent breakages that occurunder the heavy pressure that is necessary, or else the boxes had to bemade so heavy to avoid these breakages as to materially increase theircost without entirely obviating the liability of breaking.

The novelty of our invention consists in constructing the boxessentially of wrought metal in separate pieces riveted or fastenedtogether, as will be herewith set forth, and distinctly pointed out inthe claims.

In the accompanying drawings, Figure lis a front end elevation through atier of three boxes, the middle one of which is shown in section. Fig. 2is a plan view of one of the boxes with the mat removed. Fig. 3 is asideelevation of Fig. 2. Fig. 4 is a detailed perspective view of one of thetop pressure-plates.

The same letters of reference are used to indicate identical parts inall the figures.

A is the division-plate of the box, made of wrought metal, andpreferably1 rectangular in form. Upon the top of this plate is secured arail, B, of wrought angle-iron or steel, secured by rivets or bolts, andsurrounding the two sides and front end vof the plates.

Resting upon the plate A is a cast-metal,

block, O, which may be secured to the plate A by any means desired, andwhich forms the plunger on which rests the :mat D, Fig. 1, of anysuitable construction, that carries the meal from which the oil is to beexpressed.

The space a between the rail B and the plunger C forms the gutter toreceive the oil that is pressed from the meal, and conducts it into thetrough or pocket E, provided with an outlet,b,that is bolted orotherwise fastened to the under side of the rear end of plate A.

To form the side and end walls of the box proper, we preferably employangle-shaped steel plates F, which are partially recessed on their uppersides in the under side of the plate A, as seenat c, Fig. l, so that thelateral strain is partially borne by the plate A, and is not thrownentirely upon the rivets or bolts which unite the side and end walls tothe plate A.

The side and end walls of the box may beV of separate pieces or of asingle piece, as desired, and instead of steel, wrought angle-iron maybe employed,though we consider steel the best and more durable.

To avoid the necessity of planing and polishing the underside oftheplate A, forming the inside top of the box, we employ a separate brassor nickel plate, G, which fits snugly within the box, and may befastened thereto, if desired, and which has its edges thickened to formbeveled ribs d to ll the angular corners of the box, and to give therequired shape to the edge of the meal-cake. This plate G has likewiseprojections e upon its under surface in the form of the heads ofbutton-head bolts, which are provided to keep the cloth which inclosesthe meal from slipping when pressure is applied. These projections maybe about two inches apart all over the lower surface of the plate G.

From the above construction it will be seen Y that we have produced avery simple telescopic box, which will bear an exceedingly heavy strainwithout liability of breaking, and which can be made much lighter thanthe ordinary cast-metal boxes.

Having thus fully described our invention, we claim-u 1. A box foroil-presses, composed of a wrought-metal division-plate, A, supportingthe plunger O, and to which is securedon its upper side an angle-irongutter-rail, B, and on its lower side angle-shaped cast-steel side andend. walls, substantially as described.

2. A box for oil-presses, composed of a wrought-metal division-plate, A,supporting IOO the plunger G, and to which is secured on Vits plates G,provided with projections e, subupper side an angle-iron gutter-rail, B,and stantially as and for the purpose' described. on its lower sidepartially recessed angleshaped side and end walls constructed ofYjSP'DAJIgN wrought metal or steel, substantially as described.Witnesses:
